Thermal decarbonylation of quinones in the presence of hydrogen. Sakai, Tomoya; Hattori, Masayuki (Dep. Chem. React. Eng., Nagoya City Univ., Nagoya, Japan). ACS Symp. Ser., 32(Ind. Lab. Pyrolyses, Symp., 1975), 457-75 (English) 1976. CODEN: ACSMC8. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 22, 26, 67, 25 The kinetics and mechanisms of decarbonylation, in the presence of H at 500-600.degree., of polycondensed aroms., of the type produced by hydrocracking of coal or heavy petroleum residues, were studied by anal. of the products of quinones pyrolysis in quartz ampuls. Noncatalytic thermal decarbonylation was examd. 84-11-7 and 106-51-4 which are cas registry numbers of substances are two of reagents here. for 1,2- [524-42-5] and 1,4-naphthoquinone [130-15-4], p-benzoquinone [106-51-4], 9,10-anthraquinone [84-65-1], and 9,10-phenanthrenequinone [84-11-7]. The latter two were cleaved at the central ring, initially forming fluorenone [486-25-9], then Ph2 [92-52-4] and C6H6 [71-43-2], with CO the main by-product. Kinetic data and a discussion of the competing polymn. and polycondensation reactions were given. .

Organic matter in the Triassic formations of Bulgaria

Organic matter in the Triassic formations of Bulgaria. II. Disseminated organic matter in the Middle Triassic carbonates from the holes near the city of Knezha (northern Bulgaria). Vuchev, V.; Kovachev, G.; Petrova, R.; Stoyanova, G.; Tsakov, K. (Geol. Inst., Sofia, Bulg.). Neft. Vuglishtna Geol., 4, 3-22 (Russian) 1976. CODEN: NVGEDV. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) The sediments studied comprise a set of marls, limestones, and dolostones from 3 formations, which are low in org. matter (<0.6%) but contain normal values of bituminoids and a high degree of autochthonous bituminoids. The Fe content was low, but a high content of nonreduced Fe3+ was found in some samples from great depths and under anaerobic conditions. C14-4.0 alkanes with C22 predominant, isoprenoids, and isoalkanes were identified by gas chromatog. in the heptanol ext. of the bituminoids. Fluorenone [486-25-9] was isolated from th EtOH ext. of the alc.-C6H6 bituminoid fraction of cores from depths <4000 m. This ketone is known in petroleums and is used in their correlation with bituminoids. The Triassic formations were impregnated with migrational and mature bituminoids, which indicates their potential as a source of petroleum.
